Outstanding Energy Saving Results

1. Controls harmonic distortion to less than 5% and corrects the power factor up to 99%.

2. As a replacement for traditional brake resistors: A high-watts brake resistor is usually applied to a traditional AC motor drive to absorb the excess regenerative energy generated by motor spinning and frequent braking, and then dissipating the excess energy as heat (see Figure 1).. Using brake resistors as an excess energy solution not only creates additional hardware but also occupies more space. The Delta AFE2000 series provides a new solution: instead of dissipating regenerative energy as heat, it converts regenerative energy into reusable electricity and sends it back to the mains, which reduces total energy consumption. The AFE2000 series is a cost saving and environmentally-friendly product (see Figure 2).

REG2000 Series

A traditional drive system used for inertia load work generally performs rapid deceleration, braking and positioning. When its motor is in generator mode it produces large amounts of regenerative energy that must be consumed to maintain a stable DC bus voltage and safe operation. The traditional method to solve the regenerative energy problem is to install a brake resistor. While it is easy to install and is low cost, it takes up a large amount of space and requires installing additional devices to dissipate the heat. This method provides limited efficiency and wastes the regenerative energy.

Delta’s REG2000 series is capable of collecting and converting your system’s regenerative energy into reusable electricity for the ultimate in energy savings. The installation process is as simple as installing a brake resistor, but with only half the size and better efficiency. The REG2000 is your best green energy solution for power regeneration.
